My invention relates to a ‘novel lamp socket
having snap fastener means for attaching it to a
supporting structure.

modi?cation of the prong structure. ‘
An object of my invention is to provide a lamp
2o socket ,which may be easily and detachably se
cured to'a panel or other supporting structure
without the use of rivets or fasteners other than
shown in Fig. 3. This collar is in the form of a
?at ring and has a pair of diametrically opposed
notches ‘I and a pair of detents 8. These detents
are formed by making dents in the ring adapted
to engage the lugs on the base of a lamp. Be- 5
side each of the detents is an ear 8'v bent down
in such a position that it does not interfere with
the passage through the collar. of the base of a‘
lamp but acts as a positive stop for the lugon each
side of the lamp base when the lamp is rotated 10
during the process of installation, as will be more
fully explained.

The outer edge of ‘the ring 6 is folded over ?at
against. the main part of the ring to form a
common base for the ?ngers i0. Thus the ?ngers .15
I0 actuallyvextend from the ring 6 and I prefer
to make them all in one piece as is best shown in .
Fig. 3. The prongs are preferably made of spring
steel and are shaped sothat they diverge from
the base and then converge towards a common 20
point. In a modi?cation'of the above form of
prong, I‘have bent the ends of the prongs back _
the snap fastener means provided byv the socket towards the socket, as is shown in Fig. 8.; _
Assembled in the cylindrical part of the shell i
itself.
25 A further object of my invention is to provide i is an electrical contact memberfor the purpose 25
a lamp socket for the installation of lamps in of transmitting current to the lamp“ I have
shown (Fig.3) a’ conventional contact member
comparatively inaccessible locations such as be
hind an instrument panel. Also a feature of my il soldered or otherwise permanently fastened to
the end of the wire 4 and having a collar ii. The invention is the fact that the lamp may be in
30 serted in the socket before the socket is attached spring I3 urges the member I i toward the lamp 99
‘ to the supporting structure.
Thus a lamp that
. is to be used behind a panel may be inserted‘
from the front.
.
by pressing against the collar i2 and thecap 2,
thus assuring a good electrical contact.
.
One method of operatingthe socket is as fol
Referring ?rst" to the ‘socket per se, I have lows: ' The base ll of the lamp I5 is pushed be-'»
35 shown for purposes of description one whichis tween the free endsv of the ?ngers Ill which nor-o 35
adapted- particularly for use with a single contact mally lie on'a circle considerably smaller than
lamp of the type now almost universally used in the base of the‘ lamp. Thus they exert a spring
gripping action on the base when it is pushed be: “ I
' automobile installations. It should‘ be remem-'
‘bered, however, that my invention is not limited tween them. The base is pushed in until the lugs 1
40' to this particular type of socket and that changes . IS on the base of the lamp pass through the m
may be made to accommodate different types of notches 'I. The inside diameter of the ring is such '
that it ?ts snugly around the base of the lamp to
lamps without departing from the spirit and in
tent of myinvention.
'
' The main part of the socket as illustrated con
.45 sists of a tube-like shell I which serves as a means
for manipulating the installation as well as being
a base for the fastening and lamp-engaging parts.
Thisshell I is cylindrical in shape for the greater
part of its length and is' provided with a cap 2
50 at one end (Figs. 2 and 3). Through this cap I
‘
have pierced the aperture 3 to permit passage of
the conductor wire 4. At the opposite end, the
cylinder ?ares outwardly into a cone-shaped por
tion and terminates in a ?ange 5. Secured to
65 the shell ‘i by the ?ange I is a collar 6,‘ as best
I prevent any undesirable lateral motion of the two
parts relative to one another.
_
.
‘
when the lugs on the base of the lamp have u
been passed through the notches 'l the lamp is _
rotated clockwise until the lugs are stopped by
the ears 8“, at which point theyautomatically
snap into the detents 8 where they are held by
the action of the ?ngersulll and‘the spring I}, ‘m
which has been compressed by the base of the
lamp during the assembly.
'
v
- The next and ?nal step is to insert the lamp
and ?ngers in the aperture which has'been pre
pared in the supporting structure l1 and is larger “
2
2,125,843
than the diameter of the lamp but smaller in
diameter than the circle in which lie the outside
edges of the fingers III at the tips of‘ the bends
II‘. The pressure, of course, is exerted on the
shell I which acts as a handle for the assembly
and the socket is pushed flush against the sup
port where it is held by the spring action of
‘the ?ngers Ill. The lamp and socket may be.
removed as a unit or ‘the lamp may be removed
from the reverse side of the panel as with an
ordinary socket.
Another method of assembly is to insert the
socket in the aperture before inserting the lamp
in the socket and then insert the lamp between
the ?ngers Ill. Thus my improved device may
be used whether or not the device to which it is
attached is accessible from both sides.
While I have illustrated and described a pre
ferred form of my invention I do not wish to be
limited thereby as the scope of my invention is
best de?ned by the following claims.
